TECHNICAL FIELD

The present disclosure relates to an optical lens, in particular to acamera optical lens suitable for handheld devices such as smart phonesor digital cameras, and camera devices such as monitors or PC lenses.

BACKGROUND

With an emergence of smart phones in recent years, a demand forminiature camera lens is gradually increasing, and a photosensitivedevice of a general camera lens is no other than a charge coupled device(CCD) or a complementary metal-oxide semiconductor (CMOS) sensor. Sincea progress of a semiconductor manufacturing technology makes a pixelsize of the photosensitive device smaller, a current development trendof electronic products is that their functions should be better andtheir shape should be thinner and smaller, the miniature camera lenswith good imaging quality has become a mainstream in the market. Inorder to obtain better imaging quality, the lens that is traditionallyequipped in a mobile phone camera adopts a three-piece or a four-piecelens structure. Besides, with a development of technologies and anincrease of diverse demands of users, and under a circumstance that apixel area of the photosensitive device is shrinking and a requirementof the system for the imaging quality is improving constantly, afive-piece, a six-piece and a seven-piece lens structure graduallyappear in a lens design. There is an urgent need for ultra-thinwide-angle camera lenses which have good optical characteristics andfully corrected chromatic aberration.
